Sucking up pride - question about rear wheel removal
« on: May 21, 2010, 08:40:49 AM »
1978 CB750 (K8)

Got the front wheel off no problem.  Went on to start removing rear wheel.  Removed the cotter pin from the rear wheel axle.  Tried to loosen the axle nut with a wrench, but it wont budge.  I think I'll have to use a tool that I can get more leverage on, but thought I'd ask here first.  Info, tips, tricks, and appropriate tool recommendations appreciated.

a BFH always helps!

is it rusted? hit it with some PB Blaster or Liq wrench.
if not, slide a 2'+ section of pipe over the handle of your wrench

Hey rynanza,

The same thing happened to me when i tried to take it off of my 78 750.  I soaked it, used a big fing wrench, yelled at it, kicked it and nothing worked.  Ended up having to take it over to my buddies who had an impact wrench.  Previous owner tightened the crap out of it.  I just brought over the whole thing, swingarm and wheel together.  Pretty heavy but it rolls  ;D

Fair question.  Yes, I was wrenching the lefty-loosey direction.

I keep a 36 inch or so long piece of fence post around for this very reason....longer handle=more torque with less effort!

More leverage the better. I've got my breaker bar breaker, which is about a 8 foot long piece of natural gas line. I always use that thing to break axle nuts loose, (on FWD cars) and almost always break my breaker bar in the process. Good thing craftsman has a lifetime warranty. I've busted things loose with that than an impact couldn't budge.

Soak it with PB or whatever, leave it overnight or a day. Get a good socket on it, pipe if you need it and it should come off. I would be leary of heat due to the bearings.

Well I bought an 18" craftsman "flex handle" (http://tinyurl.com/36uk634), a 24mm socket, and a big can of PB Blaster spray.  Came loose without putting a pipe on the handle.  Success.  Thanks all.

My breaker bar is a 10 feet long pipe, its kind of unnecessary but it will be there for the nuts no one else can break!
Its hard to be wrong when you know nothing!
